So I just got my car back from the shop after having them install the V2 differential mount and prothane subframe bushings and had them do a 4 wheel alignment and the car still clunks when pushing on the accelerator.

Where do I look next? The clunk is better and isn't noticeable when just maintaining a speed, but if I go WOT then it still clunks.

Have you checked the u-joints on your drive shaft? They clunk when worn out. New drive shaft pretty cheap and an easy install if you have a lift.

Meanwhile, do everyone a favor. Sign in, go to User CP menu (upper left), click Edit Signature and add your Z model, year, shifter, turbo or NA, etc. Saves you having to add it to every post. (Guys here go crazy if you don't lock your Q to your specific Z every time you post...They just ignore questions without enough info) Then click Edit Avatar and you can add a little Z pic under your nick. Cool. You are solid here. Thanks.

I haven't checked u-joints yet, thanks for the tip, plus the advice about signature.

try shaking the exhaust system. loose or poorly installed exhaust/muffler can cause noise. happened on my son's 85T after magnaflow installed. shop made good on it and apologized.
